To all 'wh-0m, it may concern,.-

Be itknown that 1,5 Esse LiNcoLN Hommes. citizen of the United States,and a resident of Butte, in the county of Silverbow and'Sta-te of Montanadiave inventeda new and Improved Dam,- of `which the following is a full, clear, and exact description.

The invention relates to metal dams, such as shown and described in the application for Letters Patent of the United States, Serial No. 178,856, tiled by me October 28, 1903, and allowed July 9, 1904.

The object ot' the present invention is to provide a new and improved dam for rivers and other waterways to permit of utilizing the dammed-up water for use in power plants, for irrigation, and other purposes,`the dam being arranged to prevent or retard'the corrosive action of the Water and air on the metalwork of the dam, to properly brace the dam and hold the same against tipping over in an upstream direction 'when the Water is Withdrawn,'and to protect the structure against ice, logs, and other floating matter.

The invention consists of novel features and' parts and combinations of the same, as will be more fnllydescribed hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings,

forminga partei' this speciiication, in which Y similar characters oi' reference indicate correspondingpartsin all the views.

Fig. 18 is a sectional side elevation of the same von the line 18 18 of Fig. 17, and Fig. 19 isa side elevation of one of the posts of themain dam structure.

The dam extending across a waterwayifx consists in its general construction of a dam structure B, formed partly of metal and partly of concrete, the said structure being embedded at its bottom in a transverse recess A in the bottom A of the Waterway, and the said strncture is also embedded at itsends inthe sides or banks of the Waterway, so, aste dispense with abutments and other masonry, and the said dam structure B is braced by bracings in the form oi truss-rods C, eif'tending on the upstream side of the dam and connected with upstream anchorages D, held in the bottom A' of the waterway, the said truss-rods C being embedded in concrete which forms a wing for the concrete of the dam structure B.

The foundation of the dam structure s similar to the one shown and described inthe application above referred to*that is, it con` sists of an upright transversely extending metallic plate E, resting on the bottom of tbe said recess A2, formed transveraelyin theway tervvay, the said plate being provided at its lower end with metallic strips E to form a broad bearingface orthe said plate. The

concrete for the dem structure embeds .the

plate E and the remaining portion of the recess z is filled viiith hydraulic' cement, concrete, or other material, as plainly indicated in Fig. 1,`to securely hold Athe foundationplate and its concrete portion in position in the bed of the waterway. .s l

'On thetop of'the foundation-plate E are set posts' F, spaced suitable distances apart and each consisting, preferably, of two spaced double L-beams F and 'Fi and 8,) connected with each other at`the'upstream side by a plate Fto the projecting side of which is secured the facing of the dem structure B, the said facing consisting of metal see Figs.` 5, 6, 7,

'resem Y is @ne or more sluice'ways Q are provided for the main dam structure E, and each sluiceway Q is arranged preferably midway between adjacent bracings, and each sluiceway is preferably in the i'orm of a casting set in and secured to face-plate G, as plainly shown in Fig. 5, reference being also had to Figs. l and 2. On the upstream side of the sluiceway Q are formed suitable guideways for a gate @j to slide in in a vertical direction, the said gate being held on the lower end of a rod Qi, provided at its upper end withrackteeth Q3, in mesh with s pinion Q4, (see Fig.

-1 1,) secured on one end of a shaft Q7, 'mounted to turn vin a suitable bearing Q7, attached to a facing-plate C- and extending through the concrete iillingi at both 'faces thereof.

On the downstream end of the shaft Q5 is secured a hand-.wheel Q7, which when turned by the operator causes the shaft Q5 and the pinion Q4 to rotate, so that the pinion Q4 acts on the rack-teeth Q3 to cause the gate Q to slide upward o r downward, according to the direction in which the hand wheel Q7 is turned. In order to hold the rack Q3 in engagement with the teeth of the pinion Q4, a retaining pulley or roller Q7 is provided, (see 11,) engaging theback of the said rack and journaled in suitable bearings formed on the main bearing QG.

l distance below the hand-wheels Q7 is arranged a transversely extending runningboard R for the operator to stand on while turning the hand-wheels Q7,- the said runningboard'tR being supported on brackets it, at-

tached to the downstream face of the main structure B, By the arrangement-described it will .be seen that the wheels Q7 and the running-board R are located under the. spillway P, which :ith/us forms a protector or hood to preventwater passing'over the spillway from reaching the` operator manipulating the wheels Q7.

The metal structure and the concrete for the main dam structure B may be differently arranged, especially/when it is desired to build aheayieiand stronger dam. For instance, as shownfin Figs. le, 15, and 16, each post F 1s formed oi two members FG and F7, spaced'V apart 'endhaving flanges Fs extending in opposits directions and at obtuse angles to the members F il, as will be readily understood by reference to Fig. 16. Thernetal facing of the darn in this case is preferably formed of two plates G" and G2, secured to the oppositely-disposed flanges F801 adjacent posts, and the facs-plates G' and G2 are arranged at an obtuse angle relative one to the other and their adjacent ends are connected with each The truss-rods C are connected bytheir pins C with the spaced members F7 and of each'z post. 7

In order lio-support the concrete filling 1*", a

support is provided, consisting, essentially, of transversely-extending tubes or pipes S, havpiate F ing theirends formed with interior screwthreads engaged by bolts S,extending through the members F and F7 of a post, the bolts S also passing through the spacing-blocks F" between the members F7 F 7 of the post, and the said ends of each tube S abutting against the opposite faces of adjacent posts. To thc several tubes S are vsecured vertically-extending grate-bars S2 by the use of suitable clip.- bolts S3 and clip-bars S4.

By reference to Fig. 16 it will be seen that the concrete filling Y is only on the upstream side of the dam structure B; but this filling i7 is joined by the concrete fillings I for the several bracings. rEhe filling i7 also passes between the spaced posts F and F7 and is retained in position therein by a connecting- 1, riveted or otherwise fastened to the flanges F7 of the members F7 and F7 at the downstream side of the dam structure. plates F70 posts.

in the modified form shown in Figs. 17, 18, and 19 each vertical post is formed, essentially, ot' three dat members T, T', and T2, of which the members '.1 and T are the outside members and the member T2 is the middle member, placed between the members T and T', the three members being riveted or bolted together. The members T, T', and T2 for a post of considerable length are each made in sections, the sections breaking. joints, as plainly indicated in Fig. 19, to` give the dcsired strength to the post. The outside inembersTand Tare provided'ou the downstream side of to which 'the face-plates Gf4 are riveted or otherwise secured, the said face-plates G4, as shown, being preferably curved and made of one single piece instead of three parts, as shown inFig. 16 and previously described.

.The support for holding the concrete filling l in place on this post (T T T2) consists oi' tubes S7, similar to the tubes S previously described and likewise fastened to adjacent posts by bolts S. (See-Fig. 17.) inthis case the metallic grate-su pport, cousistingof the gratebars S2, is omitted, but the same may be employed. The truss-rods C for the post shown in Fig. 17 are provided with i'orlrs'l, straddling the members E, T', and Tloi' the correl extend the entire length of the spending post and secured to the same by the trusserod pin C1, members. l

By the arrangement described and shown extending through all the the metal-Work ot' the dam, with the excep' ,tionof the cap N and the gates and their operating mechanisms, is embedded, and hence protected lby the walls of concrete, hydraulic cement, or like material against theeorroding influence of the water and air to insure long life of the dani.
